  • inter vehicle communication technical issues on vehicle Control Application
    IEEE Communications Magazine, 1996
    Co-Authors: M Aoki, H Fujii
    Abstract:

    Mutual exchange of status data between vehicles in close proximity is the basis for safe vehicle operation. Application areas range from driver assistance/warning to fully autonomous driving. To enable this data exchange we need an intervehicle communication (IVC) system. Vehicles involved in mutual data exchange form a kind of local area network; however, the characteristics of this network are quite different from those of conventional networks. The configuration of this kind of network changes from time to time, in terms of organization, proximity group, group position, and relative position; therefore, it is very challenging to establish. The authors have been working on this problem from the point of view of communication media and protocol. The characteristics and requirements of IVC are discussed, and several preliminary communication protocols are proposed. The authors also present some experimental results from the implementation of a function integrating communication by infrared ray with a gap-measuring technique by the vision system.

  • OTM Workshops - Aspect-orientation of Control Application code for distributed automation systems: The TORERO approach
    Lecture Notes in Computer Science, 2003
    Co-Authors: Marcus Tangermann, Kai Lorentz, A.p. Kalogeras, Christian Schwab, Aggeliki S. Prayati
    Abstract:

    Besides the programming of the Control Application code of a distributed automation system (DAS) and the functional allocation of the Control Application code to the specific devices that the DAS consists of, an important point is the implementation of communication related code to map to the underlying communication platform and to realise the collaboration of the distributed Control Application code. Due to the real-timeliness and even time-criticality of DAS Applications, the correct handling of real-time constraints has to be considered. This paper presents an aspect-oriented approach for weaving the communication related code into the distributed Control Application code by means of AspectJ [AspJ03], an extension for aspect-oriented programming with Java, and gives a comparison to other approaches. In addition to the description of the weaving process and the presentation of a demonstrator example, considerations about the usability of this concept and some restrictions will be stated. This work is part of the research project TORERO, which is funded by the European Commission under the IST program.

  • Intelligent system for prediction and Control: Application in plasma spray process
    Expert Systems with Applications, 2011
    Co-Authors: A.f. Kanta, Ghislain Montavon, C.c. Berndt, M.p. Planche, C. Coddet
    Abstract:

    Parametric drifts and fluctuations occur during plasma spraying. These drifts and fluctuations originate primarily from electrode wear and intrinsic plasma jet instabilities. One challenge is to Control the manufacturing process by identifying the parameter interdependencies, correlations and individual effects on the in-flight particle characteristics. Such Control is needed through methods that (i) consider the interdependencies that influence process variability and that also (ii) quantify the processing parameter-process response relationships. Due to the large amplitudes of the drifts and fluctuations, the strategy to adopt would depend on the required corrections to apply to the in-flight particle characteristics. Artificial intelligence is a pertinent tool to reach this objective. The system is flexible in order to permit a full Control based on pre-defined rules aiming at maintaining at constant values in-flight particle characteristics (average surface temperature and velocity) by adjusting in real time the arc current intensity, the total plasma gas flow and the hydrogen content whatever the fluctuations.

  • ETFA - Aspect orientation and object orientation of Control Application code for distributed Control systems in TORERO
    2005 IEEE Conference on Emerging Technologies and Factory Automation, 2005
    Co-Authors: Marcus Tangermann, Christian Schwab, Anthony Luder
    Abstract:

    The Application of distributed Control systems is one of the main trends in current automation. Here, besides the programming of the Control Application code and its functional allocation to specific devices, an important point is the implementation of communication related code to exploit the underlying communication platform and realise the collaboration of the distributed Control Application code. Due to the real-timeliness and even time-criticality of Control Applications, the correct handling of realtime constraints has to be considered. This paper presents two approaches for integrating communication related code into distributed Control Application code. One integration method is based on the Application of AspectJ, an extension for aspect-oriented programming with Java, and the other method is based on ordinary object orientation applying standard design patterns.
